摘要： Transceiver architectures for supporting multi-band radio frequencies are disclosed. According to one aspect of the present invention, a number of processing channels are designed, each for one specified carrier frequency. A number of switching means is provided to ensure that a processing channel is properly selected for a specified carrier frequency. Each of the processing channels includes at least an amplified and a low-pass filter, where the low-pass filter is automatically programmable in response to a wireless standard (e.g., Wi-Fi or WiMAX). A single voltage oscillator (VCO) is used to support operations of each of the processing channels.

摘要： To provide greater flexibility in wireless communication design and implementation, a device and method for implementing media access control (MAC) layer functionality without using an embedded processor for MAC layer functions. A key table stores connection identification data and communicates the connection identification data to a transmit control module and a receive control module to configure and control data transmission and reception, respectively. This use of dedicated hardware, rather than an processor, to implement MAC functions simplifies the design and construction of devices which wirelessly communicate with each other.

摘要： A combined encoding/syndrome generating circuit is segmented into multiple-cell blocks that operate in parallel during encoding operations to produce interim sums. The interim sums are then combined to propagate a sum across the system, from the first cell to the last cell. Each cell includes a Galois Field multiplier and an associated update adder and register. A block of two cells includes two sets of associated Galois Field multipliers, registers and update adders, and a block feedback adder that produces the associated interim sum by adding together the products produced in parallel by each of the cells. A block with more than two cells includes additional feedback adders that operate in parallel to selectively combine the products produced by the plurality of cells, and produce an interim sum that includes a contribution from each of the cells in the block. The system then adds together the interim sums produced simultaneously by the various blocks, to propagate a sum across the system. Also, the interim sum from a given block is combined in parallel into the products produced by the respective cells of the next block, to include in the update signals that are fed back to the associated registers the contributions from each of the previous cells. During syndrome generation operations, the cells essentially operate independently to produce the syndromes. The current system includes more feedback adders than the conventional Fettweis-Hassner circuit, however, the delay through the current system is reduced from that of the conventional system, since many of the feedback adders in the current system operate in parallel.

摘要： A process is described for shrinking gate lengths and poly interconnects simultaneously during the fabrication of an integrated circuit. A positive tone photoresist is coated on a substrate and is first exposed with an alternating phase shift mask that has full size scattering bars which enable a gate dimension to be printed that is ¼ to ½ the size of the exposing wavelength. The substrate is then exposed using a tritone attenuated phase shift mask with a chrome blocking area to protect the shrunken gates and attenuated areas with scattering bars for shrinking the interconnect lines. Scattering bars are not printed in the photoresist pattern. The process affords higher DOF, lower OPE, and less sensitivity to lens aberrations than conventional lithography methods. A data processing flow is provided which leads to a modified GDS layout for each of the two masks. A system for producing phase shifting layout data is also included.

摘要： Utilizing contact printing as the second exposure within a double exposure attenuated phase shift mask (APSM) fabrication process is disclosed. The process defines the shift pattern within the attenuated layer of the APSM using a first exposure, such as electron beam (e-beam) writing. The attenuated layer may be MoSi, MoSiO, and so on. The process then defines the border pattern within the opaque layer of the APSM using a second exposure. The second exposure employs contact printing, utilizing a contact exposure mask. The contact printing process may align the contact exposure mask over the wafer on which the APSM is fabricated utilizing a camera and an image storage system storing an image of this wafer.
